Review: Love this stuff - I bought this because it helps balance my ADHD medication. We’ve been using it for 6 months(2nd time Purchasing) What I like most is it’s not another pill to take, easy flavor to put into any drink. Overall, I’d recommend this for anyone who wants a calming stress reducer that’s not another pill
Review: Helps anxiety & sleep - I have anxiety which interferes with my ability to sleep. I have started taking this 30 minutes before bed time and it has helped tremendously to relax and calm my brain. For any other nerds like me that like to know how about the supplement and how it works, here is info from Psychology Today about L-theanine: L-theanine promotes relaxation and facilitates sleep by contributing to a number of changes in the brain: Boosts levels of GABA and other calming brain chemicals. L-theanine elevates levels of GABA, as well as serotonin and dopamine. These chemicals are known as neurotransmitters, and they work in the brain to regulate emotions, mood, concentration, alertness, and sleep, as well as appetite, energy, and other cognitive skills. Increasing levels of these calming brain chemicals promotes relaxation and can help with sleep. Lowers levels of “excitatory” brain chemicals. At the same time it is increasing chemicals that promote feelings of calm, L-theanine also reduces levels of chemicals in the brain that are linked to stress and anxiety. This may also be a way that L-theanine can protect brain cells against stress and age-related damage. Enhances alpha brain waves. Alpha brain waves are associated with a state of “wakeful relaxation.” That’s the state of mind you experience when meditating, being creative, or letting your mind wander in daydreaming. Alpha waves are also present during REM sleep. L-theanine appears to trigger the release of alpha-waves, which enhances relaxation, focus, and creativity. One of the appealing aspects of L-theanine is that it works to relax without sedating. That can make L-theanine a good choice for people who are looking to enhance their “wakeful relaxation,” without worrying about becoming sleepy and fatigued during the day.

## Features

- FROM MEDITATING MONKS TO YOU — Thousands of years ago, Buddhist monks discovered that green tea helped with their meditation. In 1949, Japanese researchers extracted L theanine from tea leaves and showed it was the active calming ingredient. Today, SBR Nutrition, a leader in liquid vitamins and minerals, offers the highest quality L theanine liquid, with 225mg per serving, in a refreshing lemon flavor. Monks did not take L theanine capsules, pills, gummies, or powder. Neither should you.
- THREE WAYS L THEANINE WORKS — Boost "calming" chemicals. L theanine increases serotonin, dopamine, GABA, glycine, which together stimulate well-being and happiness, pleasure, calm, ; affect cognition, appetite, digestion, immune function, pain perception, and sleep. Reduce "excitatory" chemicals. L theanine lowers corticosterone levels, relieving stress, improving cognitive function. Enhances alpha brain waves. L theanine elicits relaxation, focus, and creativity.
- TRIED-AND-TRUE BENEFITS OF L THEANINE – L-theanine helps you fall asleep quickly and easily and improves sleep quality. L theanine may improve sleep quality in attention-challenged children.

### ⭐⭐⭐⭐⭐ Quick relief from anxiety
*by J***G on February 27, 2022*

I'm ordering these drops for the ninth time. I have tried many versions of L-Theanine, but keep coming back to the MAX. It's easy to take, and more importantly, provides almost immediate results without any downsides or side effects. I would use the MAX even if it tasted nasty because it is so effective. Fortunately, the flavor is pleasant, thanks to the lemon extract that appears on the short list of added ingredients. No sugar, salt, gluten, soy, or other potentially problematic substances. The formula does include stevia, which sometimes gives me headaches, but apparently there's not enough in the MAX to trigger those. I realize not everything works for everyone, but this has been a lifesaver for reducing my anxiety, almost as potent as prescription benzodiazepine
